PS3MFW Builder - Want to make your own PS3 custom firmware? This simple GUI can help you out! It now includes a proper Windows installer!

RedDot-3ND7355 and B7U3 C50SS have returned with a much-need update to their PS3MFW Builder application. Like previous releases, this small GUI allows you to build your own 4.XX custom firmware (up to 4.55) without much risk of a brick. It should be noted however, that CFW or OFW 3.55 or below is required to install anything you make. This build adds a full Windows installer and updated 4.5x tasks. Those looking for a 4.60 compatible version will hopefully get one soon. Despite its many anti-brick measures, harming your system is still possible with any unofficial PUP this app generates. Use at your own risk!

Installation Guide

Run the Setup "Install Our MFW Builder.exe."
